testhello.sh is not meant to be run standalone; it requires you
to set PREFIX.  It's already run by demo-*.sh, so you don't really
need to run it yourself; if it fails, it will leave an error message
at the end of the demo-*.sh output.

What you saw could have been caused by setting PREFIX to /home/jamoore/emb/tools.

Here's what I'd suggest:
Clear any environment variables you set earlier (e.g. by logging out and then in again),
then verify that PREFIX is not set (e.g. env | grep PREFIX should be empty),
then run

   cd /home/jamoore
   rm -rf emb/tools
   cd crosstool
   rm -rf build
   demo-i686.sh > log 2>&1 &
   tail -f log

(demo.sh is kind of silly, and I may as well delete it from the next release.)
